When endangered Hainan gibbons started making risky leaps across an area mowed down by a landslide, researchers provided them a rope bridge.

Environment

Jumping ‘snake worms’ are invading U.S. forests

These bad-news invaders are spreading across the United States. As they turn forest debris into bare ground, soils and ecosystems are changing.
